Went ahead and took a picture for yah. The right way is to use the black knob in the upper right hand of the picture. OR you can use the phillips screw in between #2 and #3 throttle bodies..

There is a adjustment screw between the 2 and 3 cylinder on a nytro on the front side of the throttle bodies. There is a locknut with a allen head bolt to adjust, screw it in for more rpm.

Thanks for the great picture. A little confused their are three adjustment you can use for adjusting low idle? Earlier before the last two post came out I turned the phillips screw out a turn. Seemed to adjust idle up but once warmed up bouncing from 1500 to 1750 not staying steady. Didn't let warm up for ten minutes though. Should I put screw back in the orignal position and try one of the other adjustments. Do you turn the black knob out for more idle or in.

No, you were using the flat blade screws used to sync the throttle bodies. Thos can be used to raise idle but shouldnt be. The is a singular screw with a lock nut on it on the FRONT of the throttle bodies between number 2 and 3 cylinder. The screw is a allen, the only allen adjustment screw on the throttle bodies. Again, its on the front facing side of the throttle bodies, not the top or back, the front.
